媒体融合环境下DRM生态体系建设

Construction of DRM Ecosystem in Environment of Media Convergence

随着宽带中国战略和融合媒体的持续推进,高清、超高清等高质量内容的快速发展,内容提供商对于数字内容版权管理系统提出了更高的需求。同时,内容制作和分发的云化需要内容加密和内容授权采用分布式架构实现,广电总局TVOS的发布和推行也将推进基于硬件可信环境的智能终端的发展。本文研究了国际上主流的DRM生态环境,探讨面对新环境的内容保护需求,提出基于云计算的分布式DRM体系架构。

Content providers have heightened their requirement of content protection because of the promotion of media convergence strategy and the rapid development of high quality content, such as HD,UHD etc. Content production and content distribution that are implemented in cloud need the implementation of content encryption and content distribution in a manner of distributed architecture. TVOS operating system will promote the development of intelligent terminal based on the TEE environment of hardware. In this paper, we discussed the international DRM ecosystem, made analysis of the requirements for content protection and proposed a DRM architecture based on cloud computing.
